Healthy Streets

From a cyclists point of view these look a great improvement. Dividing north and south turning traffic either side of the triangle rather than having to swing right onto Green Lanes like present - which is always congested by parked cars. Nice big cycle boxes too always feel much safer at the front of lines of traffic than tucking in alongside or poking out in front.

Not 100% sure how southbound Green Lanes traffic turns onto Alderman's Hill though??

It’s not clear to me what the impact on local roads will be of this closure, particularly if the junctions of Green Lanes and Fox Lane and with Broomfield Lane are still being worked on.
The notice in the Enfield Gazette (page 36) gives the diversions as:
Southbound; Green Lanes, Bourne Hill, The Bourne, High St N14, Cannon Hill, Aldermans Hill.
Northbound: Green Lanes, North Circular, Powys Lane, Aldermans Hill.
The note hand delivered locally from the London Highway Alliance says that Devonshire Road will remain open.

While the Triangle end of Aldermans Hill is closed (17 July to 7 October) buses will be diverted as follows:

121
The 121 will not serve any of its normal stops in Green Lanes north of the North Circular or any stops in Aldermans Hill. It will instead be diverted along Bowes Road and Wilmer Way, rejoining its normal route in Cannon Hill.

W6
Towards Edmonton the W6 after the Broomfield Park stop the W6 will be diverted along Grovelands Road, Burford Gardens and Bourne Hill, rejoining its normal route in Hedge Lane. It will not serve the stops at Palmers Green Station, Lodge Drive, Fox Lane or Bourne Hill.
Towards Southgate the W6 will run via Bourne Hill, Caversham Avenue and Old Park Road. It will not serve the following stops: Bourne Hill, Fox Lane, Lodge Drive, Palmers Green Station.

(Thanks to Donald Smith for providing this information)

What about the 329? There's a notice at the Aldermans Hill/Powys Lane junction (seen driving north) directing the 329 down Aldermans Hill. This implies a Green Lanes closure south of the Triangle, but directs it down to the closed Triangle unless it too will use the Lakes estate rat runs. Perhaps Devonshire Road..... Obviously there must be more information about this apparent conundrum.

The 329 diversions are overnight (starting at 9pm) this week, when they will be resurfacing the Green Lanes/Broomfield Lane/Oakthorpe Road junction. The 121 will be also be affected and will run via the North Circ and Wilmer Way. The 329 won't be affected by the Triangle work, which starts on the 17th.

This week overnight northbound cars along Green Lanes are being diverted via Ecclesbourne Gardens, Oakthorpe Road, Riverway, The Grove and Lodge Drive.

Does anyone know, now that the W6 is diverted along Grovelands and Burford, whether one can just hail them as they pass, or do I need to trek either to the Broomfield Park stop or the top of Hedge Lane?

Unfortunately, there is no hail and ride on the W6 diversion route. The hail and ride stops at the top of Hedge Lane and the "Broomfield Park" stops on Aldermans Hill are in use, but the bus won't stop anywhere in between.

Donald Smith suggests complaining to TfL - 0343 222 1234 option 6.

I successfully hailed one at the Fox Lane/Grovelands junction on Wednesday morning, and got let off at the Fox Lane/Caversham junction on the way back.

It would be quite odd if a route with hail and ride sections elsewhere didn't permit hailing on such a long stopless section.

The temporary route for the W6 is supposed to be via Grovelands Rd & Burford Gardens in one direction and Caversham Ave and Old Park Rd inthe other. I look out over the Fox Lane/Grovelands/Burford junction - and today the W6 has been zipping across in both directions! Anyone know what's going on? A diversion from a diversion is quite unusual!

Seems to be back to 'normal' today (Thursday) - at least, no buses going south on Burford/Grovelands.

All sounds fantastic to me, and Pin Oak a perfect choice.
